1 2.04.9(1) (a) <br />' (a) Soil Horizons. <br />As of the drafting of this application, all surface disturbance <br />' necessary for operating the mine has already occurred. Refer <br />to Drawing, 2.04.3(2)(a)-1, Existing Land Use, for the surface <br />' disturbed areas. When State Highway 133 is relocated, there <br />may be a requirement for relocation of some of the facilities. <br />' tae do not know where the highway location will be or when it is <br />proposed. After final data is received, we will notify the <br />' Division. <br />A soils study has been conducted in the disturbed area of the mine <br />' by SCS. In this survey the SCS used either soil series or soil <br />association as their mapping units. The surface of the disturbed <br />' area has been determined as one mapping unit by SCS, i'nit 77C- <br />Breece Loam. This mapping unit has a small total acreage in the <br />' study area and occurs on the floodplains of the P:orth Fork of the <br />Gunnison River. <br />Following is a description of the SCS Mapping ['ni.t for the distuubed <br />area: <br />' b:apping Unit 77C-Breece Loam <br />Position: Alluvial fans, floodplains and terraces <br />' Drainage:.
